Insert login information using pass and a dmenu-compatible application (e.g. dmenu, rofi -dmenu, ...). A short
|
||||
demonstration can be seen here: https://i.imgur.com/KN3XuZP.gif.

USAGE = """The domain of the site has to appear as a segment in the pass path,
|
||||
for example: "github.com/cryzed" or "websites/github.com". Alternatively the
|
||||
parameter `--unfiltered` may be used to get a list of all passwords. How the
|
||||
username and password are determined is freely configurable using the CLI
|
||||
arguments. As an example, if you instead store the username as part of the
|
||||
secret (and use a site's name as filename), instead of the default configuration,
|
||||
use `--username-target secret` and `--username-pattern "username: (.+)"`.
|
||||
|
||||
The login information is inserted by emulating key events using qutebrowser's
|
||||
fake-key command in this manner: [USERNAME]<Tab>[PASSWORD], which is compatible
|
||||
with almost all login forms.
|
||||
|
||||
If you use gopass with multiple mounts, use the CLI switch --mode gopass to switch to gopass mode.
|
||||
|
||||
Suggested bindings similar to Uzbl's `formfiller` script:
|
||||
|
||||
config.bind('<z><l>', 'spawn --userscript qute-pass')
|
||||
config.bind('<z><u><l>', 'spawn --userscript qute-pass --username-only')
|
||||
config.bind('<z><p><l>', 'spawn --userscript qute-pass --password-only')
|

config.bind('<z><o><l>', 'spawn --userscript qute-pass --otp-only')
